Canon EF 70-210 mm f/ 4 Lens

Cheap, easy

Weaknesses:

Constructive, sucks dust, second-hand copies are often caught with the condensate on the inner lens. Sharpness is not used to that seen in the examples, =)

Comments:

The lens is not liked

Very compact and lightweight for this focal range. Always take to trip. Operative zoom. Perfectly sharpness of image from 5.6. At the 4 bit soft, I use mainly for portraits. A small built-in lens hood. Convenient filter diameter 58.

Weaknesses:

Glares, noise focusing, vignette at max aperture

Comments:

Compared with 70-210 / 4. I thought I'd buy it if the results are better. But in almost all apertures except 4 this lens gives a picture not conceding in quality L lens. A softness in the aperture I even like, the portraits come out softer and hide imperfections. In the end, left a 70-210. A very good lens. To quickly focused, turn off the switch Macro;)

Very good for the $ 120 spent.

Weaknesses:

Poor construction rim

Comments:

Decent picture even with an open aperture, and not inferior in my opinion the prime Canon 50mm F1, 8, jammed to the F5, 6. Fast enough, though noisy autofocus. Very comfortable and superfast push / pull system zoom.
